Basic principles of operation
35
v Temperature probe is being used
z pH measurement only:
Integrated
temperature probe of a
conductivity measuring cell is being used
y pH measurement only:
Integrated temperature probe of a D. O.
probe is being used
k D. O. measurement only:
The salt content is taken into consideration.
The salt content refers to the salinity
according to the IOT table
n Conductivity measurement only:
Temperature compensation "nLF" is active
q Conductivity measurement only:
Temperature compensation "lin" is active
7 Conductivity measurement only:
No temperature compensation "TC off"
3 Only when the StirrOxG D. O. probe with
integrated stirrer is connected:
Operating with the integrated stirrer
1 Only when the StirrOxG D. O. probe with
integrated stirrer is connected:
Displays an error on the socket of the stirrer
(see also section 14.5)
0 Conductivity measurement only:
T
Ref
= 20 °C is selected
as the reference temperature
5 Conductivity measurement only:
T
Ref
= 25 °C is selected
as the reference temperature
+ With ion selective measurements only:
Reference measurement active
- With ion selective measurements only:
Blank value correction active
